Uber moves forward with massive SoftBank investment

Uber has raised billions in capital since its founding, but a new investment deal could be its most crucial yet -- and also its most complicated.

The ride-hailing startup said Sunday that it has reached an agreement for what could be a massive investment from SoftBank(SFTBF), the Japanese conglomerate, after months of speculation about a possible deal.

"We've entered into an agreement with a consortium led by SoftBank and Dragoneer on a potential investment," Uber said in a statement Sunday. "We believe this agreement is a strong vote of confidence in Uber's long-term potential."

Uber did not provide an update on the size and structure of the agreement, but a source familiar with the matter said it was essentially unchanged from earlier reports.

CNNMoney reported last month that SoftBank was looking to invest around $1 billion in Uber at its current $69 billion valuation. SoftBank is also expected to invest billions more buying up shares from existing shareholders at a discounted rate, depending on demand from sellers.

SoftBank, however, struck a sharper tone in a statement released Monday.

Rajeev Misra, CEO of SoftBank Investment Advisors, said Uber had agreed to move forward with the investment "after a long and arduous process," but stressed that a final deal is contingent on getting enough Uber insiders to sell their stakes at the right price.

"By no means is our investment decided," Rajeev Misra, CEO of SoftBank Investment Advisors and a board director of SoftBank Group, said in a statement provided to CNNMoney. "We are interested in Uber but the final deal will depend on the tender price and a minimum percentage shareholding for SoftBank."

SoftBank is said to want at least a 14% ownership stake in Uber. Otherwise, it could walk away from the deal.

"If conditions on share price and a minimum of shares are not satisfactory for the SoftBank Group side, there is a possibility the SoftBank Group may not make an investment," SoftBank Group said in a separate statement Tuesday.

The dueling statements are just the latest example of SoftBank publicly needling Uber over a multi-billion dollar deal months in the making. SoftBank CEO Masayoshi Son has repeatedly teased the possibility -- some might say threat -- of investing in Lyft instead, including as recently as this month.

The stakes are high for Uber. If the deal falls apart, SoftBank's money could make its way to its chief U.S. rival, just weeks after Lyft announced a $1 billion investment led byGoogle(GOOGL)'s parent company.

If the SoftBank deal goes through, it would function like a mini-IPO that helps tide Uber over until it actually goes public in 2019 as planned.

The SoftBank investment isn't just about the money, however. It's also key to reforming Uber's dysfunctional board and bringing a detente between warring factions: former Uber CEO Travis Kalanick and early Uber investor Benchmark.

As part of the agreement, Kalanick has agreed that he cannot fill the three board seats he controls in the future without majority approval by the board, according to two people familiar with the matter. Kalanick blindsided Uber in September by appointing two new members without notice.

Benchmark, in return, has agreed to put on hold its lawsuit against Kalanick over his control of the three board seats, with plans to drop the case if and when the SoftBank deal closes, according to the sources. The case had been set to go to arbitration.

To pave the way for the deal, Uber previously agreed to add six new seats to its board, two of which will go to SoftBank. Uber's board also adopted a new voting system that will further lessen Kalanick's influence.

"Upon closing, it will help fuel our investments in technology and our continued expansion at home and abroad, while strengthening our corporate governance," Uber said of the deal in its statement.
